And if you have a good amount of BTC, don't put them on CEXes, especially to stake do something else in the long run.
That would need to be considered too, in my opinion.

What don't you like about investing in bitcoin or crypto? This is the same passive income - bought for price X, then sold for price Y. No active actions are required from you, like in trading, for example. Just hodl!

When investing, you also, in a sense, freeze your money for a certain (or indefinite) period.

But staking on dubious platforms is even worse than keeping your money in bank deposits (in this case, there is at least some insurance from the state, and not every crook can get a banking license).

I think OP searched for the options besides holding.
Being proactive like that is good, but not with BTC, in my opinion.

I don't like keeping my bitcoin in the custody of third part and I think that the best way you can generate passive income from your bitcoin is by simply hodli and that will do the magic for you. Keeping your coins with a third-party is risky and there is no guarantee that you coins are safe with them. Don't be decieved because bitcoin is not fiat that used be used for such activities, but a reliable asset that you shouldn't gamble with.

What is Nu card? I am getting multiple options so not sure which one you are referring to. I would like to try that!

I don't think any such similar products available in the crypto market. Because cryptocurrency is volatile so it will be really disastrous for a company to predict it's price and build a business with a fixed rate of return. Probably that's the main reason no such product exists in the crypto market.

Staking is possibly the only way to generate passive income in the crypto market.

Passive income with your bitcoin is possible of course but it is risky since you earn money by storing your bitcoin on centralized platforms, it is not a good idea because these platforms control your coins.

There are great risks in storing bitcoin on centralized platforms since you may lose your coins at any time for various reasons as we all know, and the returns from that are not great for bitcoin, in my opinion Hold is much better in the long run.

If there were decentralized platforms that offered such a service while keeping bitcoin in the wallet it would be great, but as far as I know there is no such thing for bitcoin, it is only available for altcoin.

Isn't it risky to store bitcoin on any platform?, there's indeed a benefit from it if there's a platform that give passive income per year but as others have said it is risky to let other group or a company to hold your bitcoin. Well, it's up to you if you want to risk it but I prefer not doing it since there's something like that for fiat where you can earn a percentage of what you deposited on your account. How about staking or investing in a casino. I have tried it before with yolodice if I remember correctly where I invested my funds to their platform which will be added to their bankroll and can stop it or let it continue whenever you want. Anyway, I don't know any similar platform or if there's still something like that.

Staking could have been the best features that is close to what you are asking, many investors have locked their cryptocurrency in some platforms and are earning passive income from the return on this locked coins, but most people do this with altcoins and not Bitcoin since giving up your control and freedom of ownership of Bitcoin is something that most Bitcoin holder's dont like to do most of the time, so for that we are sure that only ethereum USDT and other coins with centralized features are risked for all those income generating programs.

Most Bitcoin holder's already know that holding their Bitcoin for a long term based could also be taken as passive income generation mechanism, so for that all that they need to do is to buy Bitcoin hold them in their personal wallets, and do nothing wait for the market to appreciate before taking profits in the most passive ways possible for them.

Have you observed the lending services in the forum? If you’re a lender, you can lend BTC and expect repayment in BTC. However, these days, stablecoins are becoming the more common option, but even so, a 10% monthly interest is still a great rate.

If you’re really into Bitcoin, you can always convert the USDT payments into Bitcoin as soon as you receive them. That way, you ensure you benefit from any price growth in the long run while still earning a steady income from the lending.

At this point in the market, it seems the question isn't anymore where to make passive income. The question is where to safely do it. Because it's everywhere. Which exchange doesn't actually offer it? Binance, ByBit, OKX, and the rest offer such opportunities. Web wallets, desktop wallets, mobile wallets all offer similar opportunities as well. Even hardware wallets such as Trezor and Ledger offer passive income opportunities.

Also, it isn't just the annual yield that you will possibly make money from. You might also qualify for certain airdrops. Others also provide you some kind of points. All of these could be additional sources of passive income from your invested amount.
